    • PROBLEM TO BE SOLVED: To provide methods for producing phosphorus pentafluoride and hexafluorophosphate by which high-quality phosphorus pentafluoride can be produced from an inexpensive low-quality raw material while suppressing production cost. SOLUTION: The method for producing phosphorus pentafluoride is characterized in that phosphorus pentafluoride is separated by bringing a carrier gas into contact with a raw material containing at least phosphorus atoms and fluorine atoms and thus making phosphorus pentafluoride extracted into the carrier gas. The method for producing hexafluorophosphate is characterized by reacting phosphorus pentafluoride obtained by the method for producing phosphorus pentafluoride with a fluoride according to the following reaction formula to form a hexafluorophosphate: sPF 5 +AF s →A(PF 6 ) s (wherein 1≤s≤3; and A is at least one selected from the group consisting of Li, Na, K, Rb, Cs, NH 4 , Ag, Mg, Ca, Ba, Zn, Cu, Pb, Al and Fe).
